    Hi scientists,

    What songs would you put on a soundtrack for NASA Solar Week? ;-)

    Thanks!

    Hello! I will tweeting some sunny songs all this week using the hashtag #NASASolarWeek! So far I have tweeted:

    Here Comes the Sun by the Beatles https://www.youtube.com/watch?v=xUNqsfFUwhY
    Good Day Sunshine by the Beatles https://www.youtube.com/watch?v=6e01nNA02vw
    Why Does the Sun Shine? by They Might Be Giants https://www.youtube.com/watch?v=3JdWlSF195Y
    Why Does the Sun REALLY Shine? by They Might Be Giants https://www.youtube.com/watch?v=sLkGSV9WDMA
    Both of the above songs by the Beatles have been used by NASA as musical wake-up calls for astronauts on the Space Shuttle and International Space Station.

    I've also been tweeting about the "sounds" made by the Sun and the interactions of the solar wind with the planets in our solar system. Sometimes they fall outside of the range of human hearing, so we need to speed up time in order to hear them.

    Here are some sounds that come directly from the Sun

    Many of the "sounds" are actually radio and plasma waves measured by instruments built where I work at the University of Iowa. The radio and plasma waves have been converted into sound files so we can hear them.

    Watch this space and my Twitter @Sputnik6400 for more spacey songs throughout the week!

    Today we have some music recorded on board the International Space Station by astronaut Chris Hadfield!
    Space Oddity https://www.youtube.com/watch?v=KaOC9danxNo
    Is Somebody Singing https://www.youtube.com/watch?v=AvAnfi8WpVE

    Today's space sounds come from Voyager 1, which has been exploring the far reaches of our solar system for more than 40 years. Voyager 1 crossed the outer boundary of our solar system, the heliopause, in 2012 and is now in interstellar space. Data from the PWS built at the University of Iowa were used to hear the plasma waves at the heliopause.

    Thursday's Solar Week songs were from Newfoundland and Labrador!
    Here is a recent cover of a song about the northern lights originally recorded by famous 1970s Canadian musicians Corey & Trina.
    Northern Lights of Labrador by Allison Crowe - https://www.youtube.com/watch?v=wMakVBzlP9A
    A musical tribute to the Apollo Moon landings and all of the challenges we face every day!
    Walk on the Moon by Great Big Sea - https://www.youtube.com/watch?v=OXoalnqD7z4
    Before GPS, sailors used the Sun, Moon, and stars to navigate the seas. NASA satellites today use star trackers and sun sensors for attitude control. Here's a song from Canadian musician Alan Doyle about a sailor and his guiding star.
    I Am a Sailor by Alan Doyle - https://www.youtube.com/watch?v=mQDzLmUsW38

    Thursday afternoon was Dr. Liz MacDonald's online presentation about the Aurorasaurus, so we had some auroral sounds from Jupiter. https://www.youtube.com/watch?v=J0XsMIerW3A

    Friday morning we had a song by The Chromatics, a singing group whose members work at NASA Goddard Space Flight Center. This song is full of facts about the Sun!

    Just in time for #NASASolarWeek, @NWSSWPC has issued a G2 (Moderate) geomagnetic storm watch for March 23 due to a coronal mass ejection (CME). Friday morning I tweeted some cool space sounds made by waves in the magnetosphere during geomagnetic storms.

    During geomagnetic storms, beautiful displays of aurora may be visible at much lower latitudes than normal. Earth's auroras produce a type of radio wave called auroral kilometric radiation (AKR). https://www.youtube.com/watch?v=w0HIsVfSLfc

    Perhaps the most famous type of wave produced in Earth's magnetosphere is the "dawn chorus" which sounds like a chorus of chirping birds at dawn. Here is an example from the Van Allen Probes. https://www.youtube.com/watch?v=UVXw7NNDmTE

    Whistler mode chorus waves can accelerate radiation belt electrons to relativistic energies, producing enhancements of the Van Allen radiation belts and the "killer" electrons that damage satellites. https://www.youtube.com/watch?v=suSNye-3tVo

    I study electromagnetic ion cyclotron (EMIC) waves, which are produced by protons trapped in Earth's magnetic field. Sometimes EMIC waves make chirping sounds like chorus.
    https://www.youtube.com/watch?v=9uB7cw1kT6I

    Electromagnetic ion cyclotron (EMIC) waves can scatter relativistic "killer electrons" out of the radiation belts so they are lost to the atmosphere. Cycles of radiation belt enhancement and loss are important to space weather.

    I hope that you have had a blast during Solar Week. I sure did! Keep on exploring our amazing solar system!
